net: luton: remove address translation after ofnode_read_resource

Removed call of ofnode_translate_address() after ofnode_read_resource
in luton_switch.c:luton_probe(); it is unnecessary since
the commit feb7ac45 ("dm: core: Add address translation in
fdt_get_resource").

Fixes: feb7ac45 ("dm: core: Add address translation in fdt_get_resource")
